Energy and carbon

Reducing our climate change impacts

Heating and Cooling

A recently completed energy efficiency project concentrated on heating and cooling in the check-in area of the international terminal. The project saw the replacement of old and inefficient drives with the latest variable speed technology, linked to carbon dioxide sensors.

This means fans moving air around the check-in area have changed from being either fully on or fully off, to ramping up and down according to demand.

This provides an opportunity for electrical energy savings when cooling is required and gas savings when heating is required.

The project achieved verified electrical energy savings of 84% and gas savings of 56%.

That's a combined monthly energy saving of an amazing 62 per cent, 175,000KWh or $11,000.

LED Lighting and Smart Controls

In 2012 all the lights, some 750, were replaced in the check-in area of the international terminal. Replacements were highly efficient and dimmable and included a significant amount of light-emitting diodes (LED). This initiative has reduced the energy being consumed, on a square metre basis, by 50 per cent.

In addition the lights are connected to smart controls that mean they respond to light levels and occupancy and can be individually set to achieve the correct light levels for tasks while also minimising energy consumption. This pushes the savings up to over 70 per cent!

The same technology has been rolled out across the rest of the ground floor and the first floor departures area of the international terminal.

The LED lights include fittings and wall washes that are coloured to add to the ambience of the gateway to New Zealand!

Energy Management

Our energy management team has been working on energy efficiency projects for many years, but in 2103 we received assistance from the Government’s Energy Efficiency and Conservation Authority, EECA, to help fund the preparation of a new energy plan.

This included the creation of a new energy policy and a three year plan that includes projects right across the airport that look at heating and cooling, interior and exterior lighting, street lights and more (see document downloads).

Working With Our Airline Partners

Ground power units are installed on our international aircraft gates which enable aircraft to plug into electricity whilst preparing for the next flight. This enables an auxiliary power unit on the aircraft to be switched off, saving fuel and reducing carbon emissions.

The ground power units are currently being upgraded with “crocodile arms” (see photo above) to increase their ease of use and overall utilisation.

The project will lead to significant fuel and carbon savings for the airlines at Auckland Airport.
